Mac, Tutorials

Are you tired of always having to open files in different applications on your Mac? Would you like to streamline your workflow and have a default application that opens all your files with ease?

Look no further! In this tutorial, we’ll show you how to make Preview your default application for various file types on your Mac.

Step 1: Launching System Preferences

The first step is to launch System Preferences. To do this, click on the Apple menu at the top left corner of your screen and select “System Preferences” from the dropdown menu.

Step 2: Opening the Default Applications Pane

In the System Preferences window, locate and click on the “General” icon. This will open a new window with several options. Look for the section labeled “Default web browser” – we will be using this section to set Preview as our default application.

Step 3: Choosing Preview as Your Default Application

To make Preview your default application for various file types, click on the dropdown menu next to “Default web browser.” Scroll through the list of available applications and select “Preview.”


  • If Preview does not appear in the list, make sure it is installed on your Mac. You can download it for free from the App Store.
  • If you want to set Preview as the default application for a specific file type (e.g., PDFs), find a file of that type in Finder, right-click on it, select “Get Info,” and then change the “Open With” option to Preview. Finally, click on “Change All” to apply this change to all files of that type.

Step 4: Verifying Your Changes

After selecting Preview as your default application, close the System Preferences window. To verify that your changes have taken effect, find a file on your Mac (such as a PDF) and double-click on it. It should now open automatically in Preview!


If you ever want to change your default application back to its original setting or choose a different application altogether, simply follow the steps above and select the desired application from the dropdown menu in System Preferences.

By following these simple steps, you can make Preview your default application for various file types on your Mac. This will save you time and effort by allowing you to open files quickly and efficiently. Now go ahead and enjoy the convenience of having Preview as your go-to application!
